FeaturesDesigned to improve the radar detection range and visibility of small targets to X-band radarIntended for small vessels with no radar fitted and enhance the RCS (radar cross section) of vessels up to 25m in lengthSurface or flush mountableControl box indicates reception of radar signals by flashing LED or switchable internal buzzerReception frequency: X band 9.32 ? 9.5 GHzDimensions : Antenna (L x W): 478 x 40.5 mm; Weight: 327 gms excl. cableState of the art Echomax Active-X-Band Radar Target Enhancer receives a signal from transmitting radar amplifies and returns a stronger signal. This increases the likelihood of detection reducing the risk of collision and helps to alert oncoming vessels of your position. Active RTE are increasingly being used on navigation buoys and their estimated power consumption can be seen using this link. Non use of the control box saves 10mA of power.
